H1: Manual and handwheel travel
3.5 Handwheel override in automatic mode
Extended Functions
176 Function Manual, 03/2013, 6FC5397-1BP40-3BA1
Example 2:
Activate path default and velocity override in the same NC block
N20 POS[U]=100 FDA[U]= 0 POS[V]=200 FDA[V]=150 . . .
POS[U]=100
Target position of positioning axis U
FDA[U]= 0
Activate path default for positioning axis U;
POS [V]=200
Target position of positioning axis V
FDA[V]=150
Activate velocity override for positioning axis V; axis velocity of V =
150 mm/min
Path axis
Syntax for handwheel override:
FD = [feedrate value]
In order to activate "Handwheel override in automatic mode", the following requirements
must have been met:
● Active movement commands from group 1:
G01, G02, G03, CIP
● Exact stop active (
G60)
● Linear feedrate in mm/min or inch/min active (
G94)
These requirements are checked by the control and an alarm is output if any of them is not
met.
Example 3:
Activate velocity override
N10 G01 X10 Y100 Z200 FD=1500 . . .
X10 Y100 Z200
Target position of path axes X, Y and Z
FD=1500
Activate velocity override for path axes; path velocity = 1500
mm/min
Concurrent positioning axis
The handwheel override for concurrent positioning axes is activated from the PLC via FC18
by setting the appropriate interface signal:
DB31, ... DBX62.1 (handwheel override active)
If the velocity parameter (F_Wert) is transferred with the value 0, then the activated
handwheel override acts as distance input, i.e. in this case, the feed is not derived from the
axial machine data (see also Section "P2: Positioning axes (Page 599)"):
MD32
060 $MA_POS_AX_VELO (initial setting for positioning axis velocity)
